Business rates calculator 2026

The April 2026 revaluation reset rateable values for every commercial property in England and Wales. For most occupiers, that means a higher bill - but not every new valuation reflects what the evidence actually supports.

This business rates calculator gives you a quick estimate of what you could save if your rateable value is reduced through a Check, Challenge, Appeal case. Enter your current rateable value, your property type, and what a fair valuation might look like based on comparable evidence in your area, and the calculator will show your potential annual saving, the surveyor's fee, and what you'd keep in year one.

It uses the confirmed 2026/27 multipliers, including the small business rate relief thresholds where they apply. It's free to use, takes under a minute, and there's no obligation to proceed with anything afterwards.
